Subject: City Council Meeting 1-9-23 HVAC Agenda Item
I will not be able to attend this evenings meeting. Concerning the proposed HVAC work, has the consultants or anyone considered heat pumps. If the City goes forward with solar panels heat pumps would be the more elegant system. Also any HVAC system (whether hear pumps or conventional) should be specified with soft start capability. This is important for the power backup system especially if it is in whole or in part going to be batteries.

Agenda Item No.: 11.B
Mtg. Date: 01/09/2023
TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM: VANESSA HEVENER, SENIOR MANAGEMENT ANALYST
THRU: ELAINE JENG P.E., CITY MANAGER
SUBJECT: RECEIVE AND FILE AN UPDATE TO THE OUTDOOR SIREN PROJECT DATE: January 09, 2023
BACKGROUND:
In Fiscal Years 2019-2020 and 2020-2021, the City Council provided funding for the Block Captain Program to investigate communication platforms in the event of complete power failure in the community. The Block Captains and City staff used funds to purchase two-way radios and when the handheld radio option proved to be ineffective, a Request for Proposal (RFP) was issued in February 2021 to solicit proposals on other communication systems. The City received one proposal from HQE Systems, Inc. (HQE).
On April 26, 2021, Staff recommended that City Council engage the services of HQE. The City Council directed Councilmember Pieper to work with Staff to better understand the evolution of the communication project and the scope of the feasibility study. As directed, Staff met with Councilmember Pieper on four occasions: May 20, 2021, July 15, 2021, July 23, 2021 and August 12, 2021. Some of the meetings with Councilmember Pieper included the Lead Block Captains Arlene and Gene Honbo. Staff also worked with Project Manager Alan Palermo and HQE to provide technical information requested by Councilmember Pieper. The Lead Block Captains, along with members of the Block Captains were in support of a feasibility study. The City Council approved a Professional Services Agreement (PSA) with HQE to prepare a feasibility study that would identify the hardware, location of the hardware, software, system integration, and a detailed cost estimate to install a siren system for the community.
At the January 10, 2022, City Council meeting Staff presented the final Feasibility Study and recommended to City Council to conduct a community survey to gauge interest for an outdoor siren system. In review of the Feasibility Study, the City Council requested information relating to the annual maintenance cost of the proposed outdoor siren system. The City Council also requested a street level map of Solution A and Solution B presented in the Feasibility Study.
On March 14, 2022, the City Council unanimously voted to amend the PSA with HQE allocating an additional not to exceed $3,500 to investigate potential co-location sites of the poles. On June 16, 2022, HQE Staff and Block Captain Leads Arlene and Gene Honbo 432
conducted a site visit at the Main Gate, Crest Gate, Eastfield Gate and the Radar Station. In early July, HQE submitted the revised Feasibility Study that included two additional options:
Solution C included the three gates and FAA Radar Station and Solution D included only the three gates.
At the August 8, 2022, City Council meeting, Staff presented potential site locations and to consider Solution D. HQE representatives were present to answer questions from Council and members of the public. HQE informed City Council that they had completed the remaining tasks of the Feasibility Study at no cost to the City, a savings of $22,814 and invited the Council to observe a demonstration of the proposed system, if desired. City Council directed Staff to seek approval from the Rolling Hills Community Association to place the siren poles at the three gate locations.
On September 1, 2022, Staff and Councilmember Mirsch attended a demonstration of the proposed outdoor siren system equipment at HQE headquarters. The demonstration included a tour of their facility where manufacturing of the equipment was conducted in-house and a demonstration simulated a test warning that would be sent out in case of an emergency. The equipment used consisted of a single 4' speaker mounted on a pole 25 feet above ground (for Rolling Hills, there would be 4-4' speakers mounted 50 feet above ground at each gate). The quality of the intelligible voice was clear and could be easily heard. The speakers could be adjusted to rotate a few degrees at a time through the use of a software application to ensure the best sound coverage.
In our discussion with HQE, it was conveyed that they were recently awarded a contract with the City of Paradise to install 21 poles and are in the process of installing them.
On September 1, 2022, Staff also attended the Rolling Hills Community Association (RHCA) Board meeting. Per Council direction, the City Manager asked that the RHCA Manager present to the Board of Directors the City's request to place the siren poles at the three gatehouse locations. During that meeting, the City's question was not presented as requested.
As a result, the Board of Directors began asking questions with respect to public safety, an area outside the purview of the RHCA. The Board of Directors ultimately did not discuss the City's request to place siren poles at the three gates. Instead, the Board of Directors requested that the RHCA Manager meet with City Staff and that the RHCA Liaisons meet with the City Council Subcommittee to discuss why the Board of Directors were not informed of the project, if the project was warranted, and concerns relating to only having one proposer submit a proposal for the project.
In addition, per Council direction, Staff reached out to the five homes adjacent to the three gates to inform them of the project. Two residences were in support, one was opposed, and the other two did not respond.
At the September 12, 2022 City Council meeting, the City Council directed the Subcommittee members to follow up with their counterparts at RHCA. On September 15, 2022, Staff made a presentation at the Rolling Hills Community Association Board meeting requesting an approval to place the siren system at the three gates. The RHCA Board expressed concerns about the health of the guard attendants who would be exposed to high levels of sound emitting from the sirens, interference with the operations of the guardhouses, and aesthetics and noise impacts on residents. The RHCA Board ultimately voted to not support the the City's request of placing the siren system at the gates.
433
Following the RHCA Board meeting, Staff contacted HQE to seek additional information on noise levels that could be heard at the base of the poles. Based on HQE’s response, the speakers will emit up to 124 decibels 50’ above ground; however, at the base of the pole, the decibel is 90 or equivalent to a hairdryer. Included in the packet is additional information on sound prepared by HQE.
At the September 26, 2022 City Council meeting, the City Council directed Staff to do the following:
seek input from the First Responders on usage scenarios when the siren system is deployed for evacuation and non-evacuation purposes and system with voice capability vs siren only
obtain information on easement requirements from the Rolling Hills Community Association
Staff contacted Los Angeles County Fire Department Chief Bennett and Los Angeles County Sheriff's Department Captain Powers to seek their input on the proposed usage scenarios and whether siren only system or a system with siren tone and intelligible voice would be the preferred option. Based on feedback received from the First Responders, their preferred option is the combined siren tone and intelligible voice because it could provide information to residents that are comprehensible regardless of the scenario (e.g., shelter in Place or mandatory evacuation). Staff has also created a flow chart to activate the siren.
In addition, on September 28, 2022, Staff submitted a letter to the RHCA requesting easement requirements for siting of poles at locations identified in Solution A and Solution B in easements held by RHCA with a response date of October 6, 2022. It is important to note that RHCA staff was present when pole locations were identified in Solution A and Solution B.
At the October 6, 2022 RHCA Board meeting, the Board discussed the item and requested that the City follow these procedures:
1. Obtain permission from the owner of the property where the siren will be placed,
2. Submit a written request to the Board for a license(s) to use the Association easement for Board review and approval. The request should include:
Site plan with the location of the pole and any ground mounted equipment indicated,
Specifications of the height and size of the pole and any pole mounted equipment Site plans should include property and easement lines, edge of pavement and property address. If the license is approved by the Board, the City would be responsible for legal and recording fees incurred for the license agreement(s). RHCA would waive fees for excavation permits.
Per Council direction, the pole locations are identified based on the "Outdoor Siren LocationStreet Level" prepared by HQE:
Solution A - Proposed Pole Locations
Siren A-1: On Blackwater Canyon Trail (behind 13 Portuguese Bend Rd) between Lower Blackwater Canyon Rd and Portuguese Bend Road

Siren B-1: On Pine Tree Lane (adjacent to 10 Pine Tree Ln) Siren B-2: Corner of Portuguese Bend Road and Fuld’s Furlong Trail Siren B-3: In the canyon on Crest Road East (east of 38 Crest Road East) Based on the discussion from the October 10, 2022 City Council meeting, Staff was directed to the do following:
seek permission from CalWater to place 50' poles at their water facilities identify City properties where the poles could be placed On October 19, 2022, Staff held a virtual meeting with CalWater representatives to discuss whether there is a possibility of installing poles in their three water facilities. CalWater representatives were open to the discussion and asked that the City provide additional information such as the specification of poles to be installed, length of access needed at their facilities, and any electronic equipment placed on poles. The requested information will assist CalWater to determine if the proposed poles would interfere with their current operations and/or any future planned activities at their sites. It may take up to the end of this year or early next year for CalWater to decide if their sites are viable options to install the poles.
HQE has been a generous partner with the City in providing additional information requested by Staff without receiving additional compensation. Given the new locations to investigate, it was necessary to obtain another proposal from HQE in order to conduct a site survey, perform a sound propagation analysis, provide systems option and cost to provide technical support to third-party entities. HQE submitted a proposal in the amount of $6,095 to evaluate up to four sites and correspond directly with CalWater on behalf of the City on technical matters.
At the October 24, 2022 City Council meeting, the City Council directed staff to engage the services of HQE to provide technical support in conversations with CalWater for $1,900.
To keep the community informed of the outdoor siren project, the City published a Special Blue Newsletter on October 27, 2022 identifying the proposed ten sites with the disclaimer that the final locations were not confirmed.
On October 28, 2022, Staff, HQE, and CalWater representatives held a follow-up meeting to discuss the proposed locations, specification of poles to be installed, length of access needed at their facilities, and any electronic equipment placed on poles. During the meeting, CalWater eliminated the following facilities for consideration due to space constraints: CalWater Reservoir #12, 23 Portuguese Bend (Water Tank Trail/Black Water Cayon/Tallyhand Rd), CalWater on Sunnyridge Rd in unincorporated LA County and tentatively allowed the possibility of installations of poles at the CalWater Reservoir #22 on Spur Lane and at 3960 Crest Road upon further review by various CalWater departments. On November 1, 2022, with 435
assistance from HQE, Staff submitted the requested document to CalWater for their review.
Staff anticipates to receive a response from CalWater in the next two weeks to determine if any follow-up steps are warranted.
Subsequent to that meeting, the City published another Special Blue Newsletter on November 3, 2022, updating the residents of promising news in which CalWater had tentatively allowed two facilities as possible sites for the installation of siren poles. Following that publication, Mr.
Frederick Lorig submitted an email on November 7, 2022 to Staff and the City Council to express his concerns.
At the November 14, 2022 City Council meeting, the City Council directed Staff to eliminate the CalWater facility on Spur Lane and look into two other locations: Fire Station 56 and Rancho del Mar High School, located at 12 and 38 Crest Road West.
On December 5, 2022, Staff, HQE and representatives from CalWater, Los Angeles County Fire Department, and Palos Verdes Peninsula Unified School District conducted separate consultation visits at the three proposed sites to assess the properties and answer questions from the respective agencies. All three agencies were in support of having the poles placed at their properties and were open to assisting the City with its outdoor siren project.
DISCUSSION:
At the December 13, 2022 City Council meeting, the City Council directed Staff to send out a Blue Newsletter with one side using a simplified map with the eight proposed locations and the other side with photos depicting the siren system. In addition, the Blue Newsletter should also indicate that the City Council is soliciting feedback and that this item will continue in January.
On December 22, 2022, Staff mailed the Special edition of the Blue Newsletter (attached) based on the City Council's direction. At the time of writing, the City received seven comments (attached). Due to the holiday season and to provide ample opportunity to comment on the outdoor siren project, an identical Special Blue Newsletter will be mailed on January 9, 2023 to solicit additional feedback from the community. Staff will present comments received at the January 23, 2023 City Council meeting for consideration of next steps.
FISCAL IMPACT:
There is no fiscal impact.

Comments Received from Special Edision of Blue Newsletter dated December 22, 2022
DATE NAME ADDRESS COMMENT
1. 12/26/2022 Thomas Brodie 1 Hummingbird Ln In looking at the proposed locations for the emergency warning sirens, it appears that an area of Lower (Eastfield, Chuckwagon and Outrider) would probably not be adequately covered. I am sure that considerable thought has gone into this matter. Am I missing something?
2. 12/26/2022 Allen Lay Project seems marginally useful to me. Has staff fully explored the cost of maintenance and how often it would require a test to keep it operational. I suspect the siren project has a significant cost to install and maintain therefore I am reluctant to support it.
3. 12/26/2022 Pete Hazelrigg

What the heck.
There is nothing on what these might be good for. An earlier proposal for alert towers was rejected.
Better that cell service capability be greatly improved. Since June, we have periods of no service and its sketchy otherwise at best. Though I understand this is a matter for RHCA.
4. 12/27/2022 Melissa McNabb Per the Blue newsletter just received, I wanted to give you our feedback re:
proposed siren locations.
Dustin McNabb and I prefer the following 3 locations:
A. Fire Station or Rancho Del Mar HS
B. Caballeros Ring.
C. RHCA Crest Rd East or CalWater 3960 Crest Rd.
Additionally, we prefer 30’ tall poles.
We are split on siren only (Dustin) vs. siren plus voice capacity (Melissa) 439
DATE NAME ADDRESS COMMENT
And we would prefer camouflage on the poles, IF they are in a normally visible area.
5. 12/28/2022 David S. Brown Sirens? Are we going back to the fifties? What a waste.
What we need is cell service. Then the authorities can communicate proper emergency messages, rather than just blaring obnoxious noise from speakers on towers. We can also call 911 if needed. Let's get into the nineties! The obsolete sirens will require periodic testing, unnecessarily bothering residents, perhaps unnecessarily alarming them.
Just get us the cell service we need!
6. 12/30/2022 Sue and Dave

Dear Rolling Hills City Council,
We feel the siren project would be a mistake for our city to pursue because of the following concerns:
1) The nuisance of noise to the quiet nature of the area from routine testing heard by Rolling Hills residents and the neighboring cities. 2) An alert system could be provided by good cell phone coverage. The money and energy would be better spent to create adequate cell service for our entire city. Good cell service would provide residents access to emergency services and notifications at all times.
440
DATE NAME ADDRESS COMMENT
7. 12/31/2022 Lisa L. Hancock My concerns are spending money on this unnecessary siren system. Rolling Hills is very small. I would notice if there was an earthquake or power outage without a fancy siren. Why are we doing this? I would feel safer if our cell coverage was better. And why are the sirens all clustered so close together with none down by the old Crest Road Gate? If we have so much money to spend, surely there are better uses than sirens???

Dear Honorable Mayor and RH City Councilmembers:
Thank you for requesting input on the Outdoor Siren System and for distributing a “fact sheet” to residents on siren options, descriptions, and possible locations. The sirens remain a viable option to satisfy the concerns on how residents are notified in the event of a complete power failure.
Block Captains prefer sirens with
• tone and intelligible voice, an option preferred by First Responders; • camouflaged tree facade coverings, if costs can be supported; • minimum number of poles throughout the city assuming either 30’ or 50’ poles and coverage is sufficient to notify all residents.
Safety of residents and adequate emergency communications are more important than preserving views. Feedback on EIS from residents include our cellular service is so unreliable in Rolling Hills that emergency notification may be problematic even with adequate power.
Respectfully submitted,

ARLENE AND GENE"
Your letter to the city Council is excellent. I agree with you wholeheartedly. I have only one or two comments.
1: if the 30 to 50 foot poles are offensive to some people, why can't we use volunteer homes which have a height of perhaps 30 feet and mount a pole with a siren to the side of the house.
A 20 foot pole would make a 50 foot elevation, in addition to the height of a house relative to lower lying houses. Since the houses are white, the pole would be white in addition to the siren. A voice is essential to delineate the nature of
emergency.
2: in the case of a power outage, one would need to rely on a small solar panel and a rechargeable battery such as seen on the freeway telephones.

Block Captain, Carol Marrone, agrees with the letter signed by the Block Captains and Support Team. She has an additional concern:
The outdoor sirens must adequately cover all areas of Rolling Hills especially Southfield Drive and other streets in the southern part of the city. Emergency notification via sirens of just a portion of the city is unacceptable. All residents must be notified.
Thank you.

Agenda Item No.: 12.A
Mtg. Date: 01/09/2023
TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM: ROBERT SAMARIO, FINANCE DIRECTOR
THRU: ELAINE JENG P.E., CITY MANAGER
SUBJECT: PROPOSED FISCAL YEAR 2023/24 BUDGET CALENDAR
DATE: January 09, 2023
BACKGROUND:
Each year staff develops a proposed budget calendar for City Council's review and approval.
The budget calendar includes all of the key actions and dates directly or indirectly related to the development of next year's budget, which is effective on July 1.
The proposed budget calendar related to the development of the fiscal year 2023/24 budget is attached to this report.
DISCUSSION:
The development of the fiscal year 2023/24 begins in earnest in January of each year. During this time, staff begins to develop revenue projections for the current year that become the starting point for next year's revenue estimates. This is an important first step since it establishes the revenues that will be available in the next year and, thus, to what degree the City's General Fund is balanced or unbalanced.
In February 2023, staff will bring to the City Council the mid-year report providing a status of both revenues and expenditures versus budgeted amounts. In addition, this is the first formal look at preliminary projections for the year which will establish a starting point for developing initial FY 2023/24 revenue estimates.
Later, in March, staff will bring to the Council the latest revenue projections for FY 2023/24 and a preliminary balancing strategy using existing baseline expenditures. At this time, staff will be seeking Council direction with respect to the proposed balancing strategy. In addition, staff will be seeking direction from Council regarding whether the City will be pursuing an increase to refuse rates.
During March and April, based on Council's direction, staff will work on developing the proposed budget for all funds and departments.
447
Then, over the course of three budget workshops starting in late April, staff will present the entirety of the proposed budget to Council for their consideration and feedback. The workshops will be held on Wednesday on April 19, May 3, and May 17. This will allow Council, staff, and the public to devote focused attention to the proposed budget. During these workshops, members of the public will have an opportunity to comment and provide input into the budget process.
On June 12, we will hold a public hearing, if needed, for the public to provide any protests regarding any proposed increases to refuse rates pursuant to Proposition 218. Staff will also seek any final directions from Council regarding the proposed budget scheduled for adoption on June 26, 2022.
FISCAL IMPACT:
None.
RECOMMENDATION:
Review and approve the proposed budget calendar for the development of the fiscal year 2023/24 budget.

Mtg. Date: 01/09/2023
TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM: JOHN SIGNO, DIRECTOR OF PLANNING & COMMUNITY SERVICES THRU: ELAINE JENG P.E., CITY MANAGER
SUBJECT: CONSIDER ENGAGING 4LEAF, INC. TO PROVIDE CODE
ENFORCEMENT SERVICES, AND DIRECT STAFF TO EXECUTE A
PROFESSIONAL SERVICES AGREEMENT FOR AN AMOUNT NOT-TOEXCEED $87,880 FOR ONE CALENDAR YEAR INCLUDING $68,380 FOR THE REMAINDER OF THE 2022-2023 FISCAL YEAR
DATE: January 09, 2023
BACKGROUND:
On February 28, 2022, the City entered into an agreement for code enforcement services with Willdan Group, Inc. (Willdan). The agreement was amended in July 2022 to cover the 2022- 2023 fiscal year. Willdan's code enforcement officers are professional and respectful of our residents. However, there has been a turnover of officers requiring retraining and delays in responses to cases. As such, the contract with Willdan was terminated on December 31, 2022.
DISCUSSION:
4LEAF, Inc. submitted a proposal in February 2022 to provide code enforcement services but was not selected. 4LEAF, Inc. is still interested in serving the City and has code enforcement officers available. Staff has emphasized the importance in providing an officer who can commit long-term and who is familiar with dead vegetation and weed abatement. The expectation is for a code enforcement officer to be available twice a week for 16 hours. Typically, the code enforcement officer will report to City Hall in the morning to handle paperwork and make phone calls. The officer would conduct field visits in the middle of the day and would return to the office in the afternoon for follow-up paperwork and phone calls.
The draft agreement attached to this staff report includes a clause that the consultant shall use best efforts to provide the same Code Compliance staff to the City to ensure operational consistency. If two staffing changes occur in any one-year period, 4LEAF, Inc. will be required to provide a written memorandum explaining the circumstances resulting in the turnover and provide the City with an action plan that ensures consistency. In addition, 4LEAF, Inc. shall provide a new officer to the City and incur the costs for proper on-boarding and training.
Although there are no guarantees that turnover will not occur, this would provide an incentive 451
for 4LEAF, Inc. to have committed staffing and gives the City leverage to renegotiate or terminate the agreement.
FISCAL IMPACT:
The 2022-2023 FY budget allocates $87,880 for contract code enforcement services. Willdan's final invoice has not yet been received but is estimated to total $19,500 for the first six months of the fiscal year (July 1, 2022 to December 31, 2022). This leaves the remaining balance at $68,380 for the remainder of the 2022-2023 fiscal year, which is adequate to cover 4LEAF's services of $105 per hour for 16 hours a week for the remainder of the fiscal year.
Additionally, assuming the budget remains the same for the 2023-2024 FY, it will be adequate to provide an officer 16 hours a week for the entire fiscal year.
RECOMMENDATION:
Direct the City Manager to execute a Professional Services Agreement with 4LEAF, Inc. for code enforcement services.

The Consultant shall be entitled to receive compensation in accordance with the terms of this Agreement for any work satisfactorily completed hereunder. Notwithstanding the foregoing, the Consultants shall not be relieved of liability for damage sustained by virtue of any breach of this Agreement and any payments due 454
under this Agreement may be withheld to off-set anticipated damages.
7.0 INSURANCE.
7.1 Without limiting Consultant’s obligations arising under paragraph 8 - Indemnity, Consultant shall not begin work under this Agreement until it obtains policies of insurance required under this section. The insurance shall cover Consultant, its agents, representatives, and employees in connection with the performance of work under this Agreement, and shall be maintained throughout the term of this Agreement. Insurance coverage shall be as follows:
7.1.1 General Liability Insurance insuring City of Rolling Hills, its elected and appointed officers, agents, and employees from claims for damages for personal injury, including death, as well as from claims for property damage which may arise from Consultant’s actions under this Agreement, whether or not done by Consultant or anyone directly or indirectly employed by Consultant. Such insurance shall have a combined single limit of not less than $1,000,000.
7.1.2 Automobile Liability Insurance covering bodily injury and property damage for all activities of the Consultant arising out of or in connection with the work to be performed under this Agreement in an amount of not less than $1,000,000 combined single limit for each occurrence. If Consultant or Consultant’s employees will use personal automobiles in any way on this project, Consultant shall obtain evidence of personal automobile liability coverage for each such person.
7.1.3 Worker’s Compensation Insurance for all Consultant’s employees to the extent required by the State of California. Consultant shall similarly require all authorized subcontractors pursuant to this Agreement to provide such compensation insurance for their respective employees.
7.1.4 Professional Liability Coverage for professional errors and omissions liability insurance for protection against claims alleging negligent acts, errors, or omissions which may arise from the Consultant’s operations under this Agreement, whether such operations are by the Consultant or by its employees, subcontractors, or subconsultants.
The amount of this insurance shall not be less than one million dollars ($1,000,000) on a claims-made annual aggregate basis, or a combined single-limit-per-occurrence basis.
When coverage is provided on a “claims made basis,” Consultant will continue to renew the insurance for a period of three (3) years after this Agreement expires or is terminated.
Such insurance will have the same coverage and limits as the policy that was in effect during the term of this Agreement, and will cover Consultant for all claims made by City arising out of any errors or omissions of Consultant, or its officers, employees, or agents during the time this Agreement was in effect.
7.2 Deductibility Limits for policies referred to in subparagraphs 7.1.1 and 7.1.2 shall not exceed $5,000 per occurrence.
455
7.3 Additional Insured. City of Rolling Hills, its elected and appointed officers, agents, and employees shall be named as additional insureds on policies referred to in subparagraphs 7.1.1 and 7.1.2.
7.4 Primary Insurance. The insurance required in subparagraphs 7.1.1 and 7.1.2 shall be primary and not excess coverage.
7.5 Evidence of Insurance. Consultant shall furnish City, prior to the execution of this Agreement satisfactory evidence of the insurance required issued by an insurer authorized to do business in California, and an endorsement to each such policy of insurance evidencing that each carrier is required to give City at least 30 days prior written notice of the cancellation of any policy during the effective period of the Agreement. All required insurance policies are subject to approval of the City Attorney. Failure on the part of Consultant to procure or maintain said insurance in full force and effect shall constitute a material breach of this Agreement or procure or renew such insurance, and pay any premiums therefore at Consultant’s expense.
8.0 INDEMNIFICATION. Consultant shall indemnify, defend with counsel approved by City, and hold harmless City, its officers, officials, employees and volunteers from and against all liability, loss, damage, expense, cost (including without limitation reasonable attorneys fees, expert fees and all other costs and fees of litigation) of every nature arising out of or in connection with Consultant’s performance of work hereunder or its failure to comply with any of its obligations contained in this Agreement, regardless of City’s passive negligence, but excepting such loss or damage which is caused by the sole active negligence or willful misconduct of the City. Should City in its sole discretion find Consultant’s legal counsel unacceptable, then Consultant shall reimburse the City its costs of defense, including without limitation reasonable attorneys fees, expert fees and all other costs and fees of litigation. The Consultant shall promptly pay any final judgment rendered against the City (and its officers, officials, employees and volunteers) covered by this indemnity obligation. It is expressly understood and agreed that the foregoing provisions are intended to be as broad and inclusive as is permitted by the law of the State of California and will survive termination of this Agreement.
9.0 GENERAL TERMS AND CONDITIONS.
9.1 Non-Assignability. The Consultant shall not assign or transfer any interest in this Agreement without the express prior written consent of the City.
9.2 Non-Discrimination. The Consultant shall not discriminate as to race, creed, gender, color, national origin or sexual orientation in the performance of its services and duties pursuant to this Agreement, and will comply with all applicable laws, ordinances and codes of the federal, state, county and city governments.

Upon assignment, 4LEAF’s Code Enforcement staff will be ready to respond and provide compliance solutions to code compliance cases new and existing with minimal impact to current processes. 4LEAF Code Enforcement Inspectors are qualified to do the following:

Lead Abatement
Although lead-based legislation has been around since the 1950s, nationwide regulation was not enforced until 1971 with the introduced of the Lead-Based Paint Poisoning Prevention Act (LBPPPA), which prohibited the use of leadbased paint in residential structures constructed or rehabilitated by the Federal government or with Federal assistance. In 1973, an amendment to the LBPPPA stated that lead-based paint should be removed from pre-1950 housing and structures. Our Code Enforcement team follows the requirements set forth by the State of California to ensure proper lead safe practices are taking place in removal of lead-based paint to protect citizens from exposure.
Additionally, our team participated at the National Healthy Homes Conference in 2022 in Baltimore, MD, where we spoke on the importance of Code Enforcement for Lead Paint Abatement Programs to safeguard communities.
Massage Parlor Enforcement
This scope can often be utilized for undercover stings with partnering agencies for businesses that not only violate criminal laws but also building code violations, licensing requirements, and potential massage parlor ordinances in the jurisdiction. Early detection is vital in these cases and steps include background checks and comparable effort applied. Our team has lead programs specializing in organizing and mitigating illegal actions in massage parlors.
Parking Enforcement
4LEAF has the capabilities of providing parking enforcement. This includes:

Program Analysis
4LEAF understands that Code Enforcement is an essential part of a community’s public health and safety, providing a regulatory mechanism to ensure the public’s overall wellbeing.

FROM: JOHN SIGNO, DIRECTOR OF PLANNING & COMMUNITY SERVICES THRU: ELAINE JENG P.E., CITY MANAGER
SUBJECT: FIRE FUEL ABATEMENT AND CODE ENFORCEMENT QUARTERLY REPORT FOR THE FOURTH QUARTER OF 2022 (OCTOBER 1
THROUGH DECEMBER 31)
DATE: January 09, 2023
BACKGROUND:
The Code Enforcement division provides quarterly updates on fuel abatement cases which consist of active and closed cases. The attachments show active and closed cases consisting of dead vegetation and other code violations for the fourth quarter of 2022. Also included is a list of open cases.
DISCUSSION:
During the fourth quarter of 2022, there were a total of 24 cases closes, including 20 dealing with vegetation or dead trees; 17 cases were opened, including 8 involving vegetation or dead trees. In total, code enforcement is working on 19 open cases, of which 6 deal with vegetation or dead trees.
Willdan Engineering has been providing code enforcement services since March 2022. The contract with Willdan Engineering terminated on December 31, 2022. Last month, Willdan Engineering was focused on closing cases and opened very few cases. Enforcement on dead vegetation has slowed during the winter months because deciduous trees lose their leaves and identifying a dormant tree from a dead tree can be difficult. Currently, code enforcement is being handled internally until a replacement is found. Enforcement on vegetation should increase in warmer months when dead trees are easier to identify and a new code enforcement officer is on board.
The Code Enforcement Division is continuing to use iWorQ to generate quarterly updates and track code enforcement and fire fuel abatement cases. Those reports are attached.
FISCAL IMPACT:
Code enforcement services is provided contractually and payment is made from the General Fund.
